For example, someone may add this to a drug conviction listed on their report: "I was 18, a freshman in college, and away from home for the first time. I was at a party where drugs were consumed and I was subsequently arrested for possession. Since that time I have obtained my college degree and maintained an active, drug free, lifestyle. I learned my lesson, changed my life and drugs are no longer a part of my lifestyle."
If the receive a copy of their report due to an adverse action by an employer there is no charge to add the statement. I do agree, however, that, like a credit report, background reports should be free to obtain at least once a year. There are countless cases of mistaken identity and incorrect information on criminal background reports that are often found out after it is too late. Often times too, many arrests/convictions can be removed from your report depending on the type, state, and age of arrest/conviction. Many college students don't realize the long-term repercussions of simple indiscretions. It is only after they apply for a job and are turned down because of a background check that they realize the beer they were caught drinking at age 20 in their college dorm room had bigger consequences than the $50 fine.
